Schurrle, 22, is believed to have been a target of the Blues since last season, with recent reports in Germany even suggesting that a deal between the two parties is all but done.

And after Leverkusen’s 1-1 draw against Wolfsburg on Saturday, Voller confirmed that an offer has been received for the Germany international.

“Andre is not the only player we have received offers for,” he said. “We will not get nervous. That we consider the offer is part of the business. It is all in our hands.”

Schurrle, who was on target against Wolfsburg, refused to comment on his future at the weekend.

On Monday, Bild reported that Chelsea are willing to offer €15 million for the player, who is contracted to Leverkusen until 2016. The Premier League club would also send midfielder Kevin de Bruyne, who currently is on loan at Werder Bremen, to Leverkusen for another loan stint.

However, speaking to Syker Kreiszeitung late last week, De Bruyne, 21, said: “I don’t know anything about it. My agent takes care of that and he is on holiday in Senegal for the next two weeks.”
